The reason you struggle to fall asleep at night could have a very simple fix

Alan Loughnane

This could be right up your street if you work on computers during the day…

It’s well known that the blue light emitted from your smartphones and computer screens can have a detrimental impact on the quality of your sleep.

The light from our devices is “short-wavelength-enriched,” which means that it contains higher concentration of blue light than you’ll find in natural light.

This greater concentration of blue light is known to affect levels of the sleep-inducing hormone melatonin.

Melatonin is at low levels during the day, but begins to be released a few hours before bed time and reaches its peak during the middle of the night.

Studies have shown that exposure to blue light from your phone or a computer screen in the evening can cause a resetting of your body clock to a later schedule. This means that when you go to bed, you’ll have difficulty falling asleep as your body block will have been pushed back i.e., your brain is tricked into believing it’s earlier than it actually is.

Not only this, the high frequency of the blue light from digital screens during the day can leave people with migraines, dry and tired eyes and general irritability.

People who wear prescription glasses have been able to put blue light filtering lenses as an optional extra for their prescriptions, which negates the effects of the blue light, but this can be costly.

But an Irish company called Ambr Eyewear has come up with a solution for the problem with blue light from our screens.

They’re offering a range of non-prescription glasses that block out blue light and allow people to prevent migraines and dry eyes from digital screens, and will give you a better night’s sleep.

The glasses genuinely work a treat (I’ve been wearing them for the past three weeks in work), and have noticed that my eyes are far less tired when I finish in the evenings and the quality of my sleep has certainly improved.

Prices for the glasses start at €39 and the product looks remarkably sleek and stylish.

You can find them on their website here.
